ついて以下に述べる。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) This specification relates to improvements in block type or rip-block type tread patterns in pneumatic tires, more preferably pneumatic radial tires. The following describes the results of development research on improving traction and braking performance.
この種タイヤのトレッドパターンは、とくに全。The tread pattern of this type of tire is particularly wide.
天候(いわゆるオールウェザ−)型タイヤで多くの場合

サイプと呼ばれる。Weather (so-called all-weather) type tires are often of the block type, and each block is narrow enough that they virtually overlap each other under the ground contact surface during tire load transfer to increase traction exclusively on snow. On the other hand, the block or rib block type tread pattern of general tires also has many similar notches, mainly to increase braking force in wet conditions. This cut is usually called a sipe.

る。(Prior Art) The tread pattern in which sipes are arranged is well known and there is no need to submit any literature about it, but the normal sipe arrangement is generally a so-called blind type, which is independent of the tread groove consisting of circumferential grooves and lateral grooves. There are two types: a separated type, which spans between the tread grooves that cross the tread land area and partition it, and a semi-blind type, which opens into the tread groove only at one end.

じ易いところにも、問題を残している。(Problem to be solved by the invention) The problem that this invention suffers from is the last-mentioned half-blind type, but compared to the detachable type, the conventional sipes have a higher tread land area. Although it can be said to be a compromise between blind sipes and blind sipes because of the undesirable point of reducing the rigidity of tires too much, it is insufficient to improve the snow performance of all-weather tires or the wet braking ability of regular tires. In addition, there remains a problem in that uneven wear tends to occur at the tread groove edges where the sipes are open.
従ってこの発明は、このような問題点の克服、つまりト

て、有利に充足される。(Means for Solving the Problem) The above purpose is to provide a tread with a plurality of circumferential grooves extending along the circumference of the tread at least in the central area excluding both side areas, and a tread in a direction that intersects with the circumferential grooves. It has a tread land section including at least one column block group divided by a horizontal groove extending along the width direction of the tread land section, and a large number of tread land sections cut into the tread land section from the circumferential groove to a depth equal to or less than that of the circumferential groove. Advantageously fulfilled by a pneumatic tire with sideways sipes, the sipes having a relief hole of greater width and depth at the end of the cut, which has excellent traction and braking performance. .

The cutting width should be twice, more preferably 3 to 5 times, the gap between the cuts should be 0.5 Fllm, and the depth of the cuts should be 0.5 to 1.0 times the circumferential depth. However, it is especially desirable when it comes to implementation.

Even tread patterns that include so-called ribs as tread lands without separation by 2' can still benefit from the invention.

Two separation sipes S2+3 are provided to separate each block 3' of the formation block, and at the end of the cut of the half-blind sipe S, a relief hole is bored that is larger than the width and depth of the cut, and It is desirable to make a similar relief hole, h, in the middle position of the separation sipe S2+ 33.

Under the convention that the depth is equal to or less than the depth of 1', it is suitable to be approximately the same as the leading depth, numerically about 0.5 to 1.0 times. - (Function) The escape hole helps to equalize the rigidity in the width direction along the block sipe due to the sipe cut from the circumferential groove so as to end there, and the sipe of the block under the ground contact surface. In addition to contributing to the avoidance of uneven deformation along the road, the uncut portion of the block ensures rigidity and prevents uneven wear, increasing traction on snow and improving braking force on wet roads.
